Overcoming the sensitivity–speed trade-off in two-dimensional photodetectors via a functional oxide interlayer
Jones and a bandwidth of 0.11 GHz at 785 nm, outperforming most reported on-chip photodetectors. These results establish a route to sensitive, high-speed photodetectors for optical interconnect, communications, and sensing applications.
